Abstract
This paper describes the optimization of the geometric parameters of a Marinelli beaker to maximize the detection efficiency of sample measurement with a High Purity Germanium (HPGe) detector. A Monte Carlo model was developed and the detector pulse spectrum was studied for different beaker geometries with an HPGe detector. The results show that good sample measurement with an HPGe detector can be obtained by appropriate selection of the sample height over the top of the detector cap and the beaker radius surrounding the detector. Optimum sample heights and beaker radii are recommended for different sample volumes for a given detector specification.
